The scaphoid fracture (SF) is the most common wrist fracture and it accounts for 2–7% of all body fractures.
Early diagnosis especially of a slightly or nondisplaced SF remains a problem because it is difficult to recognize it on X-ray (16% are missed on initial x-rays) and it may stay occult for 1–6 weeks. A newly proposed algorithm suggests early MRI (7–14 days after injury) to exclude SF and avoid unnecessary immobilization.
Wijetunga and authors (2018) have proposed: after injury initial...
Imaging findings OR Procedure Details
A non-union scaphoid fracture is an unhealed fracture lasting more than 6 months after injury (non-union rate between 10–15%).
Untreated non-union SF can be stable (fibrotic) or unstable (cystic and sclerotic).
Previous studies have defined union when the bridging rate is at least 50%.
A recent study (Brekke,
2018) has shown that biomechanical strength and stability are already maintained with at least 25% of bridging. It is of great importance to describe the exact location of the fracture...
Cross sectional studies (MRI/CT) remain an invaluable part of early diagnostics,
especially in occult scaphoid fracture evaluation.
Technical improvements like computer-assisted surgery,
3D printing and automatic annotation tool,
are becoming more important particularly in complex non-union SF as part of the preoperative planning.
